# Note on ... PMCD state changes: names change
# this can happen due to concurrent changes in state for _any_
# PMDA, not just sampledso we're using in this test, and probably
# from a PMDA that changes from NOTREADY to READY after a pmcd
# restart.  These are not relevant to this test, so make 'em go
# away.
